@mjb2000 I changed your topic to a V5 Question forum category the Issue category is reserved for features that are broken that might need developer attention it is not to be used for miss-configurations or configuration questions.
That is for Tracking purposes for reports. For example when you sell an item which warehouse do you want it to pull inventory from? So for example if you want PuntoSubs that you sell come out of the PuntoSub warehouse then you define that option for PuntoSub warehouse.
The reason for that is some people do warehouse to warehouse purchases… they buy into local warehouse and then move into other warehouse via purchases so its tracked. Their local warehouse may be a different building for example and they want to track inventory coming out of that warehouse and into their kitchen warehouse.
So Food sold comes out of Kitchen warehouse but purchases go into Local Warehouse.
With that new knowledge you may study it some more and decide how you want yours to work. SambaPOS lets you design your own system for that with lots of nice options. You can even add suppliers into it with Entities you probably noticed those options.
Here is a great tutorial btw it explains inventory in VERY detailed fashion and demonstrates some advanced setup options. Its a long read but worth it.
Yeah, I am really begining to appreciate how much you can customise things. I just feel bad because I am sturggling to get my head around the potential functionality and therefore I am asking a lot of questions on the forum. Fortunately everyone seems very friendly and happy to help
Do not hesitate to ask questions its the best way to learn. SambaPOS can seem daunting at first and it does take a pretty good learning curve but eventually you will get an AHA moment and realize wow I can do anything with this.
Here is a great wealth of knowledge in once place:
